supported by the wheels 7, axles 8 and cooperating journal boxes 9 and 10, in the usual manner. g

The frame 6 comprises'a wheel 1ece or side frame member 14 at each side 0 the car,

which may be, and preferably is, an Hbeam for the purpose of combining lightness and strength. Pedestals 15 and 16 are provided at the ends of the wheel piece. These pedestalseach comprise the downwardly extend ing parallel arms 17 and 18, which are connected together at their lower ends by the'tie members 19 in the usual manner. The upper portion of each pedestal is provided with an attaching bracket integral therewith," comprising the web portion21, the outwardly extendin flange 22 which is adapted to engage beneath the upper flange 23 of the wheel piece 14, and is rigldly attached thereto by suitable fastening means, as the rivets 24.

The web portion 21 of the attaching bracket is rigidly secured to the web of the wheel piece 14, the lower flange of the wheel piece being cut away adjacent each end thereof, as at and 30, for receiving these web portions. Each web K ortion may and referably is, provided tion 21 extends inwardlybeneath the lower flange of the wheel piece 14, and is rigidly connected thereto by suitable bolts or rivets.

The arms '17 and 18 are preferably providedwith wear members 27', 28, extending about the inner portion of the arms for engaging the journal boxes 9 and 10 of the axles 8.

The wheel pieces 14 are rigidly connected e transoms or cross members 31, 32, which are preferably, though not necessarily, H-beams.

with reinforcing ri s for strengthening the web "and wheel piece on The top and bottom flanges 33 and 34 of these. cross members are removed at their ends so that the web portom 35, 36, will engage the webs of the wheel pieces 14 between the -11 per and lower flanges thereof, and are rigi ly connected thereto,

as by welding, as indicated in' Fig. 4.

Suitable gusset plates 37, 38, are provided for rigidly connecting the wheel pieces to said transoms on their upper surfaces. These overlap the attaching bracket i are preferablyprovided with slots and upi i and 44 are-adapted to jections 42 at each as,at 48, 49, for accommodatin or spring-plank hangers 43, 44

rigidly connected to the upper flanges of the wheel piece and the transoms in any suitable manner, as by rivets, as clearly indicated in Fig. 3. 'As shown in Fig. 1, the outer ends of these gusset plates of the pedestals, and are secured at their outer ends to the upper flange 23 by some of the same rivets 24 that attach the flange 22 of the pedestal attaching bracket to the upper ange of the wheel piece. The gusset plates gusset plates are wardly extending apertured projections at each side thereof, to which the brake hangers 39 are pivotally connected. The gusset plate 37 is provided with an upwardly extending lug. 40, to which the slack adjusting clevis is pivoted. The dead brake lever a slot in the gusset plate,

By means of this arrangement the pivot pins for these links and levers are above the wheel pieces, whereby access may be readily had to these. pivot pins and levers for removing -the same for re lacement' or'"1'epair. Since the brake shoes 0 are operated by the brake rod 80, the radius rod 90 and retracting spring 1 00, and the conventional links and levers'in the usual manner, itis not thought necessary to further describe this well known construction;. 1

The inner ends of these gusset plates exltend along the flanges of the transoms to a oint overlapping the motor nose supporting racket 47, as will presently appear (see Fig. Portions of the upper andlower flanges of the transom members 31, 32, are removed, the spring see These gusset plates are also provided with inwardly extending projections 51, 52, which lap ast each other and are rigidly connected to t e u per flange 23 of the wheel ieces 14, as clear y shown in Fig. 3 of the By means of this arrangement these extensions on the gusset plates assist materially in strengthening the wheel pieces at each side of the truck opposite the bolster 50. The projections 51, 52, are preferably welded together after they are applied, in order to provide a smooth joint which will not only strengthen the parts but also prevent the entrance of moisture and the like w ich would 6 cause rustin and deterioration of the parts.

If desired, t ese plates may be cast integral.

Suitable gusset plates 57, 58, are also provided for rigidly connecting the lower flanges of the wheel pieces and transoms, as shown more clearly in Fig. 5. As shown; these gusset plates are provided with spring seats 55 'tively,as is-usual in such constructions. tions of the lower flanges ofthe wheel pieces providedwith side thereof, to which the Fig. 5).'

and 56, which are preferably integral therewith. These gussets are preferably integral because they are in tension, but it is understood they may be separate and also provided with lapping projections like the upper gusset plates, if desired. They are rigidly connected to the lowe'rflange of the wheel pieces and are adapted to materially strengthen said pieces opposite the car bolster 50.

Each side of the truck is provided with an equalizer member 59, which has its ends engaging the. journal boxes 9 and 10, respective-- ly, and its central portion depressed, as at 61, as is usual in such constructions. Each of these equalizer members comprises a pair of bars 62 and 63, held in spaced relation by the spacer members 64 at eachv end of the deressed portion 61, and by a central spacer lock 65. The spacer members 64 are provided on their 66, which are ada ted to be arranged below the spring seats 55,'56,, an,d in vertical alinement therewith, as clearly shown in Fig. 1 of the drawings. 1

The bolster 50 is supported from the transoms 31 and 32 by the swing hangers 43, 44, g which are connected at their lower ends by the connector member-'71 on which the spring seats 72 engage. A. lurality of'leaf springs 73' are interposed between the sprin seats 72 and s rin ca s or seats 74 attache to the under si e o eac spring seats 72 are connectedtogether by a spring lank 75, which comprises the two Z-barse 6, 77 (see Fig. 10),which are connected together at their intermediate portions b the plank 78 (see Fig. 6) The plank 8 is rovided with an opening 79 through whic the kin bolt 81, for connecting body bolster 82 an the truck bolster 50, may be inserted and removed. The king bolt '81 is adapted to be held in its elevated POSI- as clearly shown in I tion by suitable clips 81a, Fig. 10. The wheel pieces 14- are provided with brackets or loop members 83, extending inwardly for limiting theswinging moveend of thebolster 50. The

In the form of construction shown, suitable means are provided for supporting'one or more motors on the truck adjacent to the bolster construction. Only one motor is shown. As shown more or less diagrammatv ically in Fig. 3, the motor 84 is mounted on the axle 8 in the usual manner. .Since the mounting that will permit a limited vertical movement of the inner end'or nose of the motor may be employed. Since the motornose supports 86 at each side of the bolster are substantially the same, only one need be described. This support comprises the body portion 87 (see Figs. 5, 7, 9 and 10). The

body portion 87 is provided with an upwardly extending attaching portion 88, having the laterally extending wings 89 which are rigidly connected to the web of the adjacenttranso'm, as by being riveted thereto, as clearly shown in Fig. 7 of the drawings. The lower flange of the transom is cut away, as at 91 (see Fig. 9) to accommodate the upwardly extending portion 88.

The body portion 87 is also provided with an inwardly extending horizontal flange 92, and with an outwardly extending horizontal flange 93 at each side of the upwardly extending portion 88, which are rigidly connected to the lower flange of the transoms, as by being riveted thereto. Reinforcing ribs 94 (see Fig. 9) are provided for reinforcing the body portion 87 and the flange 92. The lower end of the body portion 87 is provided at each side thereof with inwardly extending flanges 95, to which are attached. connecting members 96, which extend from one motor nose support to the other beneath the spring planks 75, and not only brace the two motor nose supports but also constitute a spring plank safety hanger.

Suitable means are provided for resiliently supporting the motor nose from the motor nose support 86. In the form of the device selected to illustrate one embodiment of the invention, the body portion 87 is provided with a pair of outwardly extending flanges 97, adjacent to the under side of the corresponding transom, and with a pair of outwardly extending flanges 98, adjacent to the lower end of the body portion 87 These flanges are arranged in pairs in spaced relation. The corresponding members of each pair are in vertical alinement. and are provided with openings through which bolts 99 are adapted to extend. The" flanges 97 are provided with vertically extending reinforcing ribs 97a, and the flanges 98 are also provided with corresponding reinforcing ribs A suitable resilient unit is mounted on the bolts 99 between the flanges 97 and 98. As shown, this mechanism comprises a pair of plates 102 and 103 adjacent to the flanges 97,

mounted on the bolts 99, about which the springs 106 extend. The springs 106 encircle bolts 108, which extend through the followers 104 and 105. The plate 103 is provided with enlarged openings in alinement with the bolts 108, whereby when the device is compressed the bolt heads may extend through said opening. The followers 104, 105, are provided with countersunk openings for .receivingthe heads and nuts of the bolts 108. These followers are also provided with bosses extending about the bolt openings for positioning the springs.

The inner end of the motor or motor nose 109 is provided with a lug 110 adjacent its upper portion, which extends inwardly therefrom and is adapted to rest on the plate 102 for resiliently supporting the inner end .of the motor.

Suitable means are provided for yieldingly resisting the upward movement of the motor at its inner end. This means, as shown, comprises a lug 111 extending forwardly from the lower portion of the moto nose, and is adapted to engage beneath the plate 103, which resiliently resists the upward movement of said lug. It will be noted that the plates, springs and spring followers are so constructed that they are reversible, that is, it is immaterial which follower and plate are in the uppermost position.

In the operation of cars there is more or less swinging or swaying of the car body relative to the truck frame, due to the track curvature and the inequalities in the roadbed. And where, as in the present invention, motor generator sets for operating motors are mounted at one end only of the car, there is an unequal distribution of the weight, the end of the car opposite the motors being much lighter than the motor end, or where, for anyreason, the car is so constructed that one end is heavier than the other, the oscillation or swinging movement at the two ends of the car if similarly mounted, will not synchronize. These non-synchronizing oscillations of the ends of the car are more or less detrimental to the car and are unpleasant to the passengers.

It has been found that the swing or spring board hangers 43 at the light end ofthe car can be arranged at such an angle as to cause the oscillations at bpth endsof the car to synchronize. In Figs. 11 and 12 this arrangement is shown diagrammatically. In Fig. 11 the transom at the heavy or motor end of the car is shown by the line 31, the swing or spring board hangers by the lines 43, and the spring board by the line 75.

The arrangement of these parts at the light The difference in the angle of the links or hangers 43 is exaggerated for the purpose of illustration. The pivots on the transoms 31 moved. by the center of gravity of the will be closertogether in Fig. 12 than in Fig. 1, as indicated on said figures, The difi'erential angle will, of course, vary with the different lengths, weights and types of cars, but in all cases the angle that the hangers 43 make with the vertical will be greater at the lighter end of the car. When the hangers 43 are arranged as in Figs. 11 and 12, it will readily be seen that for the same angular movement of these two sets of hangers the center of gravity of the lighter end will move through a greater vertical height than the heavier end. Since the vertical distance car ends for any given angular movement of these hangers will vary as the sine of the angle, and since the sine varies more rapidly as the hangers approach the horizontal, it follows that these two sets of hangers may be so arranged as to synchronize in their oscillations.

It will thus be seen that a car truck is pro- I vided that is built up of separate comparatively light units, and the parts so connected and arranged as to form a light truck frame that combines lightness and rigidity.
